Rubber roofing is roofing material which contains natural rubber, often recycled tire-derived rubber, as its key or major ingredient. It often contains other ingredients such as compatibilizers, stabilizers, UV (ultraviolet light) inhibitors, and color which make it suitable for sloped roof applications. Recycled rubber roofing has a significant ecological impact today, as well as in the future when it can be recycled again and made into new roofing material. This course illustrates the environmental and performance benefits of rubber roofing and discussed why it facilitates fast and easy installation.
